Air Conditioning Nelson: Cool Summers, Warm Winters
Nelson summer afternoons get properly hot, and a north-facing living room can feel like an oven by 3pm. A reverse-cycle heat pump cools it down in summer and warms it in winter.
Yes, the same heat pump that heats your home in winter cools it in summer. In Nelson that matters, because sun-facing living areas overheat on hot afternoons. A well-sized reverse-cycle unit drops the temperature fast and runs cheaply.
Why Nelson homes need cooling, not just heating
Nelson gets some of the brightest, hottest afternoons in the country, and homes here are built to catch it. That's great in July and rough in January. North-facing living areas in the older villas around town and the newer subdivisions out at Enner Glynn and Richmond soak up the afternoon sun and hold the heat well into the evening.
Opening windows only helps so much when the outside air is already warm. A reverse-cycle unit actively pulls heat out of the room, so you can knock a stuffy 28 degree lounge back to something comfortable in a few minutes. The same unit does your winter heating, so you're not paying for two separate systems.
How reverse-cycle cooling actually works
Reverse cycle just means the heat pump can run both ways. In winter it moves warmth from the outside air into your room. In summer it flips, pulling heat out of the room and dumping it outside. Same box on the wall, same remote, one button to swap.
It also takes moisture out of the air as it cools, so a muggy room feels drier and fresher. That's handy in coastal spots like Tahunanui and Mapua where the humidity climbs on a still day.
Cooling one room or the whole house
For a single hot lounge, one wall unit does the job. If you've got a few rooms that overheat, or bedrooms that are stifling for sleeping, you don't need a separate outdoor unit for each. A set of multi split heat pumps runs several indoor heads off one outdoor compressor, which keeps the outside of the house tidy.
For open-plan homes or new builds where you want cooling out of sight, ducted heat pumps feed cool air through the ceiling into every room. It costs more up front and needs roof space, so it's not right for every home, but it's worth a look if you're renovating anyway.
Getting the install right for a sunny room
Where the indoor unit goes makes a real difference in a sun-facing room. We'll put it where the cool air reaches the spots you actually sit, not blowing straight at the couch or short-cycling in a corner. Good heat pump installation Nelson also means the outdoor unit sits somewhere shaded and easy to service, not baking on a west wall.
If you're not sure what capacity you need, our heat pump sizing calculator gives you a starting point, and we confirm it on site.

Air conditioning questions from Nelson homeowners
Does a heat pump work as an air conditioner?
Yes. A reverse-cycle heat pump is an air conditioner. It cools your room in summer and heats it in winter, all from the one unit on the wall. You just switch modes on the remote. Nearly every heat pump we install in Nelson does both.
How much does air conditioning cost to install?
For a single wall-mounted unit, most Nelson installs land in the low-to-mid thousands, depending on the size of the unit and how tricky the wiring and pipe run are. Multi-room and ducted systems cost more. We give you a fixed price after seeing the room, so there are no surprises.
What size air conditioner do I need for my room?
It comes down to the room size, ceiling height, insulation and how much sun it gets. A north-facing Nelson lounge that bakes all afternoon needs more grunt than a shaded bedroom the same size. Undersize it and it struggles on hot days, oversize it and it cycles on and off. We measure and size it properly rather than guess.
